Ball structure used in a baseball or a softball

ABSTRACT

A ball structure used in a baseball or a softball comprises a ball core; two covers enclosing the ball core; the two covers being seamed together by a seaming wire; an edge of each cover being formed with a plurality of wire holes for being passed by a seaming wire; a plurality of recesses arranged near an edge of each cover; each recess being formed between a respective one of the wire holes and the edge of each cover; a direction of each recess being identical to the seaming direction of the seaming wire; thereby when the two covers enclose the ball core by using the seaming wire; the part of the seaming wire exposing out of the covers fall into the recesses.

FIELD OF THE INVENTION

The present invention relates ball structures, and in particular to aball structure used in a baseball or a softball, wherein a plurality ofrecesses arranged near an edge of each cover; and part of the seamingwire exposing out of the covers will fall into the recesses. Thereby theseaming wire will not wear so as to increase the lifetime of thebasketball and softball.

BACKGROUND OF THE INVENTION

Referring to FIGS. 2 and 3, the prior art baseball or softball includesa ball core 10, and two covers 30 which are seamed by a seaming wire 20.An edge of each cover 30 is formed with a plurality of wire holes 31(referring to FIG. 1) for receiving the seaming wire 20.

However in above mentioned structure, the seaming wire 20 protrudes fromthe surfaces of the covers 30 (referring to FIGS. 2 and 3). Since theseaming wire 20 is easy to wear and thus break so as to affect thelifetime of baseballs or softballs. Furthermore, currently, a lower sideof each cover 30 is installed with a filling object 40 so as to form aprotrusion. However this increase the wear of the seaming wire 20.

SUMMARY OF THE INVENTION

Accordingly, the primary object of the present invention is to provide aball structure used in a baseball or a softball, wherein a plurality ofrecesses arranged near an edge of each cover; and part of the seamingwire exposing out of the covers will fall into the recesses. Thereby theseaming wire will not wear so as to increase the lifetime of thebasketball and softball.

To achieve above objects, the present invention provides a ballstructure used in a baseball or a softball which comprises a ball core;two covers enclosing the ball core; the two covers being seamed togetherby a seaming wire; an edge of each cover being formed with a pluralityof wire holes for being passed by seaming wire; a plurality of recessesarranged near an edge of each cover; each recess being formed between arespective one of the wire holes and the edge of each cover; a directionof each recess being identical to the seaming direction of the seamingwire; thereby when the two covers enclose the ball core by the seamingwire; the part of the seaming wire exposing out of the covers fall intothe recesses.

The various objects and advantages of the present invention will be morereadily understood from the following detailed description when read inconjunction with the appended drawing.

DETAILED DESCRIPTION OF THE INVENTION

In order that those skilled in the art can further understand thepresent invention, a description will be described in the following indetails. However, these descriptions and the appended drawings are onlyused to cause those skilled in the art to understand the objects,features, and characteristics of the present invention, but not to beused to confine the scope and spirit of the present invention defined inthe appended claims.

With reference to FIGS. 4 to 6, the present invention will be describedherein

As shown in FIGS. 5 and 6, the present invention is suitable to be usedin basketballs or softballs. The present invention comprises thefollowing elements.

A ball core 10 is included.

Two covers 30 enclose the ball core 10. The two covers 30 are seamedtogether by a seaming wire 20. An edge of each cover 30 is formed with aplurality of wire holes 31 (referring to FIG. 4) for being passed byusing the seaming wire 20.

With reference to FIG. 4, a plurality of recesses 32 are arranged nearthe edge of each cover 30. Each recess 32 is formed between a respectiveone of the wire holes 31 and the edge of each cover 30. A direction ofeach recess 32 is identical to the seaming direction of the seaming wire20. Thereby when the two covers 30 enclose the ball core 10 by theseaming wire 20 (referring to FIGS. 5 and 6), the part of the seamingwire 20 exposing out of the covers 30 will fall into the recesses 32.Thereby the seaming wire 20 will not wear so as to increase the lifetimeof the basketball and softball.

The present invention is thus described, it will be obvious that thesame may be varied in many ways. Such variations are not to be regardedas a departure from the spirit and scope of the present invention, andall such modifications as would be obvious to one skilled in the art areintended to be included within the scope of the following claims.

1. A ball structure used in a baseball or a softball comprising: a ballcore; two covers enclosing the ball core; the two covers being seamedtogether by a seaming wire; an edge of each cover being formed with aplurality of wire holes for being passed by the seaming wire; aplurality of recesses arranged near an edge of each cover; each recessbeing formed between a respective one of the wire holes and the edge ofeach cover; a direction of each recess being identical to a seamingdirection of the seaming wire; thereby when the two covers enclose theball core by using the seaming wire; the part of the seaming wireexposing out of the covers falling into the recesses.
